Form cancelling and refreshing in both 4.0 and 4.1

[D&J Gredler <dj...@gmail.com>]

Hi,

In Tapestry 4.0 I was using the following JS in a button's onclick handler
to cancel a form: "this.form.events.cancel()". I believe this has been
replaced with "tapestry.form.cancel(this.form)".

I was using the following JS in another button's onclick handler to refresh
a form: "this.form.events.refresh()". I believe this has been replaced with
"tapestry.form.refresh(this.form)".

(Please correct me if any of the above is wrong)

What javascript can I use to be compatible with both 4.0 and 4.1? Is it
possible?

Thanks,

Daniel

Nope...Not for this at least...Maybe I should add a big warning sign
somewhere in the 4.1 docs. I'm very much ok with breaking backwards
compatibility for this particular piece of functionality....It was a great
idea at the time, but caused many headaches for me in tacos - and also is
considered very very bad programming practive in js. (hence my
hatred/distrust of prototype...you can easily find when people started using
it more by searching through jira and finding comlaints about the DatePicker
in tap not working anymore...changing runtime behaviour of native objects is
not ok..)

I have gone to great pains to provide backwards compatible versions of all
the other Tapestry.<foo> functions though..(ie you can also submit forms via
Tapestry.submit_form() ...something like that..dopn't remember the old
function name right now)
